Well it won't have any of my custom modpacks, but it won't be long until it does, 1.7.9 should be getting mcp modding support soon. So I will be putting together a custom pack with that, and will redo 1.7.2 mods along with it and a new launcher that supports modpacks.
But thats maybe a few weeks away still, I guess my motivation will be based on mcp getting 1.7.9 out soon.
"Ok! Will it be a new version of MC?"
It has all the minecraft releases, including snapshots. Just no modpacks, but you can install mods yourself in this version, including using installers like the forge one. I guess I'll do a video tutorial on using my launcher when its properly released with modpack support.
